My Cognitive Audit: Why Three Big-Name Supplements Failed My Spreadsheet and What Finally Moved the Needle

Cognitive decline supplement tracking spreadsheet on a desk illustrating a personal brain health audit

I'm three stalls into the Allen Farmers Market, holding a bag of peaches I don't remember picking up, running Tuesday's and Wednesday's brain-health scores through my head because I left the supplement-tracking spreadsheet on the kitchen counter. Eight weeks into this particular experiment, in this stretch of retired life, and the numbers came without paper — no columns, no cells, just figures floating loose in my head, landing right where I expected them to. Thirty years of making sure a client's books balanced to the penny didn't prepare me for auditing my own cognitive decline instead. It never taught me to trust a number I hadn't printed out first.

This page carries a disclosure required under FTC Endorsement Guidelines and 16 CFR Part 255: some of the links here point to retailers I have a paid relationship with. If you buy through one, the merchant sends a commission this way, and you pay exactly the same price you would otherwise.

Three decades of making other people's books balance took an odd turn once I couldn't make my own head balance the same way. I forgot a longtime client's name mid-meeting, three times in one quarter, and started auditing myself instead of numbers that weren't mine. Fourteen months of testing followed — every supplement I could get shipped, tracked in a workbook with more tabs than any tax return I ever filed, chasing the kind of ROI that has nothing to do with dollars. My wife looked at one of the pivot tables once and asked whether I was auditing vitamins or investigating a cold case. Some mornings it's genuinely both. I never ran anything like a true placebo baseline — no fake capsule sitting next to the real one — so every comparison in that workbook is really just this month's me against last month's me. My actual method is duller than people expect: same three checks, same order, same time of day, logged into the same three columns whether I felt sharp or foggy that morning.

Quick disclosure before we go further: this page uses affiliate links, and if you buy something through one, I earn a commission at no extra cost to you. Everything I recommend is something I've personally run through my own tracking, because I'm a numbers guy, not a marketer. I'm not a doctor, not a neuroscientist — just a retired accountant trying to tell a normal fifty-something slowdown from something worth paying real attention to, so talk to your own doctor before starting anything new, especially if you're noticing real changes.

Before any of the labeled supplements, there was melatonin — an early guess that the fog was really just bad sleep wearing a disguise. It didn't move the morning score. It didn't move the afternoon one either, right where the fog always hit hardest. I filed it as a write-off and moved on to the actual candidates.

Every morning since has started the same way: a soft clack of the keys logging yesterday's focus score into a cell before the coffee's finished doing its job.

Premium Pricing Doesn't Guarantee a Return

Late last autumn I opened a bottle of NeuroPrime and felt, briefly, like I'd bought a blue-chip stock. Sleek box, confident copy, a price tag that assumed the quality was baked in already. I tracked what I called Lag Time — the seconds it takes to fish out a specific noun — every morning, same cup of coffee, same amount, because caffeine swings that number around enough on its own that I had to hold it steady before trusting anything else in the column.

Two months of entries later, Lag Time hadn't moved — same average as the week before I opened the bottle. The label promised a blend built for peak performance; the results column just sat there, flat, which is the whole risk of judging a product by its packaging instead of your own numbers. In accounting terms, I'd paid a premium for a service that never got rendered. I even built an Excel macro one afternoon correlating dosage against focus, only to realize I'd forgotten to actually take the capsule that morning — a filing error, not a data point.

A forum contact of mine, Mireille Chatham — a retired pharmacist up in Atlanta who tracks her own numbers with the same stubbornness I do — pushed back when I posted that flat Lag Time data, wanting to know if I'd accounted for dosing timing at all rather than just eyeballing "no change." Fair pressure. My scoring has always been subjective by design — I'm grading a felt sense of a word arriving on time, not running a lab — and I said as much back to her.

I've laid out the fuller comparison in my NeuroPrime vs Brain Song for Better Name Recall and Memory piece, but the short version holds up fine on its own: a high price tag doesn't guarantee a balanced ledger. NeuroPrime is also a single dense blend rather than something you'd stack ingredient by ingredient, which stops mattering pretty fast once none of the ingredients are doing anything to begin with.

Does a Bigger Bottle Mean a Better Dose?

Early spring brought Neuro-Thrive, the budget pick, and the question of whether a lower price tag could still clear a reasonable bar. A standard size-00 capsule holds about 0.91 milliliters, which I looked up purely out of accountant curiosity — and once fillers and the vague "other ingredients" line get subtracted, there's not much square footage left for anything meant to reach your brain. Ingredient lists on bottles like this read like a tax form: a handful of active lines buried under filler categories that mostly exist to take up space.

It reminded me of Form 1040 — thirty-eight lines on the first page, and if thirty-five of them are administrative padding, the real substance is buried in three. Neuro-Thrive turned out to be the high-volume, low-density type. Processing speed — the mental math I used to be fast at, back at the firm — actually trended slower across those four weeks, the opposite of what a budget experiment is supposed to prove. I also ran a separate working-memory check during that stretch, holding a short list in my head for a few minutes just to see if it stuck, and that column barely moved either.

Running the same comparison against my Six Weeks with Memory Wave notes, the pattern repeated: more pills doesn't mean more progress if the concentration isn't there. You could fill every one of Excel's 16,384 columns with data and it still wouldn't help you find five missing dollars in a bank reconciliation.

The Timing Problem That Complicates Supplement Tracking

One pattern jumped out that had nothing to do with ingredients at all: nearly every bottle says take one in the morning, and that instruction assumes everyone's morning happens at the same hour, which runs straight into whatever's going on with a disrupted circadian rhythm anyway. A neighbor of mine works night shifts as a nurse, and by her account, most of these "brain boosters" made her feel worse, not better, because her morning starts around dinnertime for the rest of us.

Before writing a word of that down, I ran the whole angle by my old friend Clifford Achebe — one of my tax clients for fourteen years before I retired, and still the guy who keeps me honest anytime something I'm about to publish edges toward medical territory. His question was simple: had I tested this myself, or was I repeating something I'd picked up secondhand? Fair point. I was reporting somebody else's data point, not my own column, so I'm passing it along here as exactly that: an observation, not a rule.

That neighbor conversation also got me thinking about how a rough week at home can tank a focus score just as fast as a bad supplement can. I started flagging high-stress days in a separate column after that, so a bad week wouldn't get blamed on whatever I happened to be testing that month.

Trading Capsules for Headphones

By midsummer I'd run out of pills worth trying and hit a wall of red cells with nothing left to test. So I tried something with no capsule involved at all: The Brain Song, an audio-based program built around sound instead of anything you swallow. The accountant in me was skeptical — you can't fit a sound wave into a size-00 capsule — but the numbers were flat enough that the risk felt small next to what I'd already spent chasing pills that did nothing.

Sitting in my home office with headphones on instead of rattling a pill bottle felt strange those first few days. By week eight, my Name Recall column — verbal recall, timed the same way every morning — had a steady downward trend in seconds, meaning faster, and it held for several weeks running instead of bouncing around the way the pill trials had. Nothing dramatic. About five percent a week, compounding, which is the kind of number that looks unimpressive until you let it run long enough.

The Genius Song stayed bookmarked in my saved-for-later tab — The Genius Song, that is — rather than running alongside Brain Song. One variable at a time, tested in sequence, instead of trying to untangle two audio programs' worth of data points in the same eight weeks. My brain, it turns out, was done being audited with chemistry and wanted a different kind of input altogether.

Fourteen Months Later, the Ledger Finally Balanced

That final pivot table tells a clean story: mental sharpness never came out of a capsule for me — it came from switching the kind of input altogether, something that actually moved the numbers instead of just making the sheet look busy. Plenty of money went toward high-end nootropics that produced nothing but rows of unchanged data.

If you're staring at your own monitor wondering where your sharp edges went, don't keep feeding the same pill bottles more money on faith. Return on a traditional capsule can be low if your body isn't processing it the way the label assumes, or if the filler-to-active ratio is worse than advertised. Sometimes fixing a broken ledger means changing the accounting method, not adding another expense to the same broken column.

Walking away from capsule logic was the actual breakthrough for me, slow as it was to arrive. If you want to see the same kind of movement in your own numbers after however many dead ends you've already hit, The Brain Song is the one thing on my whole spreadsheet that turned a sea of red into something worth the fourteen months it took to get there. Track your own results no matter what you try — an old accounting habit, but a fair one: if you don't measure it, you can't manage it.
